EISCO Ray Box: This traditional ray box features three openings, allowing two sets of pupils to use it simultaneously. The two side openings have two slots each for accommodating 50 mm slide accessories and blanking plates. A front opening provides seven grooves for accessories and lenses, designed to produce divergent or convergent rays through the slit plate when used with a biconvex cylindrical lens of 75 mm focal length. This ray box requires only a minimum of accessories to cover a wide range of optics experiments. It comes supplied with 2 meters of flexible cable, two 4mm plugs, a 12V - 24W B15 bulb, a bulb holder, a slit plate, and aluminum blanking plates. Working instructions are also included.
